Dear SQLAlchemy experts,
I'm having difficulty generating an SQL query with SQLAlchemy.
I'm trying to query a list of messages with their originator and
recipients. Each message is sent by one host to one or more hosts. Hosts
are all stored in one table (host). There are two types of messages
Hi,
For Pyramid, another interesting package is SQLTap, which provides useful
informations about execution of SQLAlchemy queries...

any solution to it, I'm just trying to find a bypass on the ORM side.
I definitively agree with SA ORM's way of handling all this. I was quite
sure in fact that there was no easy way to bypass the ORM...
Thanks anyway,

Hi,
I don't think that the solution can come from SQLAlchemy.
You may have to create a database link between your two databases to be
able to query both of them with a single instruction...

Hi all,
I am trying to do a join between two tables, each residing on a separate

Here is the table info for both. I have removed extraneous columns from

I just noticed my connection pool isn't pooling. Whenever a connection
which has been used only for reading is returned to the pool
and without real updates:
do_begin_twophase
do_prepare_twophase = False
do_commit_twophase
oci_prepared = False
no commit !
That's great, for me it works like a charm!
Do you think that this patch could be backported to a new 0.7.x release of
SA ?

Is there anyway to print the query with the params in place?
example:
products = sa.query(entity_object).filter
(entity_table.c.created_attime_object)
print products
Prints the query, but without the params.
For debugging it would be nice if it could produce something i can
paste and execute
36 matches
